Description
Technical field
The present invention relates to a kind of welding method, and in particular to a kind of plastic part welding method.
Background technology
Based on the low characteristic of plastic material heat fusion joint, the method welding plastic zero of industrial widely used plastic hot melt welding
Part, its principle are directly the face of weld of working of plastics to be heated by metallic plate, after reaching certain fusing point, withdraw from metallic plate, then
Certain pressure is applied to two plastic parts, the purpose of welding is reached.The technology is more ripe at present, but it is scarce to there is part
Point, i.e., as the solder side shape between part to be welded is irregular, make metallic plate not easy processing；Metallic plate in welding process
Preheating degree, the hot uniformity is bad affects weld strength not enough, welding effect is unstable；Metallic plate is directly connect with working of plastics
Touch, fire damage or other damages are easily caused on plastics, welding quality is affected.
With the increasingly raising of people's living standard, people put forward higher requirement to IAQ, generate
The air purifier of a variety of, seriation.The rack cover plate of conventional air purifier includes substrate and is embedded at present
Sets of transparent panels on substrate is into as the junction of substrate and transparent panel is hidden in substrate and transparent panel when fixed
Portion, therefore the method for conventional sweat soldering cannot be adopted to be fixed which.Now generally adopt the mode for fastening with glue to fix
Substrate and transparent panel, it is not only cumbersome, it is also easy to excessive glue occurs and product quality and attractive in appearance is affected.
The content of the invention
The goal of the invention of the present invention is to provide a kind of plastic part welding method, simple and effective can weld plastic part
It is connected together, and firm welding, good looking appearance.
To achieve the above object of the invention, the technical solution used in the present invention is：A kind of plastic part welding method, which includes
Following steps：
Step one, by with welding wire fixing groove the first working of plastics be placed on the work top of Suppression of High-frequency Welding Devices and fixation；
Step 2, metal welding wire is embedded in the welding wire fixing groove of first working of plastics；
Step 3, the projection of the correspondence welding wire fixing groove on the second working of plastics is embedded in the welding wire fixing groove and by high frequency
Briquetting on welding equipment is compressed；
Step 4, startup Suppression of High-frequency Welding Devices, metal welding wire generate heat in the presence of high-frequency alternating magnetic field and melt welding wire fixing groove
Inwall and projection so that the first working of plastics and the second working of plastics are closely linked.
Preferably, in the step 2, metal welding wire is that chrome faced low-carbon (LC) class pulls iron wire or do not lure the soft steel of steel
Silk.
Preferably, the pressure size that briquetting is compressed in the step 3 is 4～6Mpa.
Preferably, in the step 3, briquetting compressed the time for 6～10 seconds.
Preferably, the frequency of the step 4 medium-high frequency alternating magnetic field is 27MHZ.
Preferably, in the step 4, the heating temp of metal welding wire is 270～300 DEG C.
As above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：
1. the present invention is embedded in metal welding wire in the weld of plastic part, is generated heat in high-frequency alternating magnetic field using metal welding wire
Principle, the weld of molten plastic part are simultaneously closely linked, not only firm welding, and the working of plastics beautiful outline form after welding
See；
2. the present invention can effectively improve production efficiency, save artificial and production cost.
Description of the drawings
Fig. 1 is the welding method flow chart of the present invention in embodiment one.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described：
Embodiment one：
It is shown in Figure 1, a kind of plastic part welding method, which comprises the steps：
Step one, by with welding wire fixing groove the first working of plastics be placed on the work top of Suppression of High-frequency Welding Devices and fixation；
Step 2, metal welding wire is embedded in the welding wire fixing groove of first working of plastics；
Step 3, the projection of the correspondence welding wire fixing groove on the second working of plastics is embedded in the welding wire fixing groove and by high frequency
Briquetting on welding equipment is compressed；
Step 4, startup Suppression of High-frequency Welding Devices, metal welding wire generate heat in the presence of high-frequency alternating magnetic field and melt welding wire fixing groove
Inwall and projection so that the first working of plastics and the second working of plastics are closely linked.
Specifically, in the step 2, metal welding wire is that chrome faced low-carbon (LC) class pulls iron wire or do not lure the soft steel of steel
Silk.
The pressure size that briquetting is compressed in the step 3 is 4～6Mpa.
In the step 3, briquetting compressed the time for 6～10 seconds.
The frequency of the step 4 medium-high frequency alternating magnetic field is 27Mhz.
In the step 4, the heating temp of metal welding wire is 270～300 DEG C.
It is pointed out that the present invention is before welding, needs enter according to the shape of the first working of plastics and the second working of plastics
Row modeling, is first fixed on mould on Suppression of High-frequency Welding Devices, then is fixed and clamped the first working of plastics and the second working of plastics by mould.This
Invent that welding plastic part shape is not single, use range is very wide, need to only correspond to different plastic parts and provide corresponding
Mould.
